Hubble captures 'cosmic cascade' of UGCA 193 galaxy that looks like a waterfall; see pics

On vember 4, NASA shared a breathtaking im of galaxy UGCA 193, a constellation of Sextans that appears like a waterfall of stars captured by  NASA’s ESA Hubble Telescope. Taking to Instagram, NASA’s Goddard laboratory uploed photo of galaxy with a striking blue haze that is kwn to host umpteen young stars, some bigger than six times size of sun. “UGCA 193 appears to host many young stars, especially in lower portion of this view,” Goddard wrote in caption, ding, that mystical galaxy gives sense that “stars are falling from above.”

In a release, NASA’s Goddard explained reason UGCA 193 featured a striking blue waterfall vibrance. “Blue colour of UGCA 193 indicates stars that we see are hot,” it informed. “We kw that cooler stars appear to our eyes as redder, and hotter stars appear bluer,” it furr explained. According to NASA, galaxy gets its colouration based n mass and surface temperature of stars it constitutes. For instance, according to NASA astronauts, milky Way looks white, colour of fresh spring sw some100,000 light-years across.

Stars brightness decided 'galactic hues'

Jeffrey Newman at University of Pittsburgh said in a research that scientists at Sloan Digital Sky Survey that measured properties of millions of galaxies and brightness of its stars that decided galaxies’ hue. As per a report published in journal Newman said that red galaxies indicated rarely formed new stars, while in blue galaxies, such as UGCA 193 stars are still being born. According to Goddard, UGCA 193 ‘cosmic casce’ colour is linked to heavier stars that are able to “burn at higher temperatures resulting in a blue glow from ir surface.” Internet mesmerised at rare galaxies’ beauty wrote, “Think of each photon that gives us this im is of stars million miles apart.” Ar said, “You would think hotter would be red and cooler to be blue. Thanks for insight.”
